Consider this equation. cos(theta) = (-2√5)/5. If theta is an angle in quadrant II, what is the value of sin(theta)? NO LINKS!!!

vlada-n [284]

In second quadrant sin and cosec are positive

$\\ \tt\hookrightarrow sin^2\theta=1-cos^2\theta$

$\\ \tt\hookrightarrow sin^2\theta=1-(\dfrac{-2\sqrt{5}}{5})^2$

$\\ \tt\hookrightarrow sin^2\theta=1-\dfrac{20}{25}$

$\\ \tt\hookrightarrow sin^2\theta=\dfrac{5}{25}$

$\\ \tt\hookrightarrow sin\theta=\dfrac{\sqrt{5}}{5}$

$\\ \tt\hookrightarrow sin\theta=\dfrac{1}{\sqrt{5}}$

M<6=(5x+99)* and m<10=(3x+17)* find m<10

Ann [662]

Sorry, but it does not make sense to start with m<0 and then connect that with an "=" sign to (3x+17). Please ensure that you have shared the entire problem.

You write "m<10=(3x+17)* but provide no info regarding the value of x.

Please start over.

what is the difference between multiplying fractions and adding/subtracting fractions? complete sentances pleaseo

jok3333 [9.3K]

Answer:

See explaination for answer! Hope this helps!

Step-by-step explanation:

When multiplying and deviding, you are raising them or lowering them by a certain degree, but adding or subtractions is just combining two fractions.

Just to quickly explain the "combining" aspect, during subraction, you are combining a positive with a negative.

Solve the following polynomial expression: (5x^4-9x^3+7x-1) + (-8x^4+4x^2-3x+ 2) - (-4x^3+5x-1)(2x -7)

Answer:

Check photo

Step-by-step explanation:

It is is important to be really careful with negative signs, which is why I multiple the last two expressions together and then multiple through with the negative. It makes it a lot easier.
